Polymer elements not rendering in Android 4.1.2 and 4.2.1. Works on 4.4.2

[gngeorgiev]

You can see attached a screenshot of the two emulated devices. I also tried on a real device with 4.2.1 I would really like not to drop polymer as I would love to build a mobile app with it. Can you suggest any workaround? I would like to target at least android 4.x.x. Moreover, it seems that its the CSS that is problematic, there are no errors on the console.

Thank you guys.

Polymer does not work with the android browser that shipped in older
versions. In Android 4.4 we switched over to using Chrome as the default
browser so that's why it's working there. If you're working on a hybrid app
you can use Crosswalk with Cordova
https://crosswalk-project.org/#documentation/cordova to get support in
older browsers.

Yep, I actually saw that a few hours ago but did not have the chance to use it. I hope it will do the trick. I am gonna close this now.

Do you have any plan to get polymer work with android browser 4.0?

[robdodson]

@kildem no the old android browser is not supported

[kildem]

@robdodson I can see it isn't supported ... so you don't have any plans to support it on android 4.0 :(

[robdodson]

@kildem no sorry. That's a very old version of Android with fairly small market share and the amount of effort to try to polyfill old android browser would be pretty huge. Our support starts at Android 4.4

thanks for answer @robdodson, I have an android 4.0 e-ink e-reader. At the moment there isn't any android 4.4 e-ink device with big screen ... I hope the manufacturers will update these devices to more recent version soon. So that we can build polymer app for these devices too.

when I open a polymer website (for example polymer-project.org) in a not supported browser I can see only a blank page. Instead it would be better if the user receive a message, for example: Your browser is out-of-date. Please download one of these up-to-date, free and excellent browsers....

[robdodson]

@kildem I don't think this is something Polymer itself would implement, instead we'd leave it up to the developer. You can either try to feature detect which browser the user is on using JS or do UA sniffing server side and send down a different experience for those folks on Android browser
